The purpose of using a spray system is to ensure that the mist particles produced by the system evaporate before reaching the ground. The method to achieve this is to make the mist particles as small as possible.Even in areas with relatively high humidity, the mist can be completely absorbed by the air, fully realizing the humidification effect. The smaller the nozzle flow rate, the finer the mist droplets, the faster the evaporation, and the better the cooling effect. To prevent nozzle clogging, the water supply to the spray system must be filtered.
